Method of modelling a maintenance system

A method according to any preceding claim, wherein the component data relates to the current age or length of service of the at least one component represented in the component database, and the reliability data includes data relating to the predicted age or length of service at which the at least one component will require maintenance.

A method according to any preceding claim, wherein the computed output data is outputted to an output database in the form of a maintenance schedule, the maintenance schedule relating to the predicted time at which one or more of the components represented in the component database will require maintenance.

A method according to any preceding claim, further comprising providing a component cost database, and inputting cost data, relating to the cost of maintaining and/or storing one or more components represented in the component database, to the component cost database, the output data being computed in accordance with a predefined relationship between the cost data, and the component data and/or the reliability data.

A method according to any preceding claim, the method further comprising providing a project database on the computer system, and inputting project data associated with one or more parameters defining the maintenance system, to the project database, the output data being computed in accordance with a predefined relationship between the project data and the component, cost and/or reliability data.

A method according to any preceding claim, the method further comprising providing updated data to one or more of the databases of the computer system during the period of time covered by the maintenance system.

A method of modelling an aircraft maintenance system in accordance with any preceding claim.

A computer program stored on a computer usable medium, the computer program comprising an application including a component database and a reliability database, the application further comprising computer readable instructions for causing the computer to execute the steps of:

• prompting a user to enter component data relating to the status of one or more components to be maintained as part of a maintenance system;
• prompting a user to enter reliability data, associated with at least one component represented in the component database, to the reliability database;
• and computing, in accordance with a predefined relationship between the component and reliability data, output data relating to the predicted maintenance of at least one of the components.

A system for modelling a maintenance project, comprising a computer having a processing means, and an application program stored on a memory of the computer, wherein the application program includes:

• a component database for storing component data relating to the status of one or more components to be maintained as part of the maintenance project;
• and a reliability database for storing reliability data relating to the predicted performance of at least one component represented by the component data in the component database, the processing means being arranged to compute, in accordance with a predefined relationship between the component and reliability data, output data relating to the predicted maintenance of at least one of the components.
